It was not working for the IXXAT PCI card, at least (but I have not yet 
understodd why). Check with "$ lspci -vv" how the device is mapped and 
what IRQ number is used. The right thing is to implement a PCI driver.

As already mention, I'm currently working on a driver for the IXXAT PCI 
card. As I see it, a generic driver is not feasible as the mapping, the 
recognition of the second channel and the IRQ handling is quite different.

Is there a Linux driver on the CRROM your got with your Advantech 1680 
PCI card? That would help a lot.
